OIL-BURNER INSTALLATION.

Application filtd May 25, 1926. Serial No. 111.621.

This invention relates to im rovements in means for mountingelectricaily driven oil burners. in connection with the furnace orfirebox in which the burner is located.

Such an oil burner structure includes the burner in the firebox, asabove stated, a motor outside the firebox, and driving connectionsbetween the burner and the motor. Owing to such connections the burnerand motor must be rigidly'connected together. These members thereforeare usually mounted on a common rigid base which is partly supported bysome portion or other of the furnace. The operation of the motor sets upan unavoidable vibration and humming noise which, by reason of thecontact of the base with the furnace, is transmitted to and intensifiedby the metal of the furnace and is carried thence through all the pipingleading from the furnace. The result is that when an installation ofthis character is made the vibration and noise of the motor are verynoticeable all over the building, especially if the ap aratus is set upin an ordinary frame resi ence.

The principal object of my invention therefore is to eliminate the above0bjectionable features by mounting the burner in such a manner thatneither it nor the base contacts with any portion of the furnace, andwithout interfering with the necessary rigidity of installation. t

A further object of the invention is to provide a cover for theexternally located parts of the burner structure, so as to protect'thesame and to form a substantially air-tight enclosure about the fireboxdoor so that air for the burner must pass to the burner through anopening provided in the cover enclosure. This permits of more accuratecontrol of the air than is possible if the usual opening and fireboxdoor are used as the air intake and damper means, since owing to thenecessary members projecting to the burner through said opening, it isnot easy to mount a door therefor so as to have the desired movement andaccurate air controlling features.

Another object of the invention is to construct this covering of suchmaterial that while closely surrounding and attached to the fireboxdoor, said covering will not burn nor will itimpart any vibration fromthe motor to the furnace.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposefor which it is designed.

These objects I accomplish by means of such structure and relativearrangement: oi parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of relierence indicate correspondingparts in the several views:

Fig. 1 is a side elevation of my improved adjacent the firebox andformed integral therewith or rigidly secured thereto in any suitablemanner is a rigid extension 4. T his extension is clear of the floor andprojects intothe furnace through the opening: 2 in spaced relation tothe sides and bottom thereof. Supports 5 project upwardly from the innerend of the extension and support a burner 6 of suitable form. such asfor instance as is shown in my Patent No. 1,582,- 552 dated April 27th,1926. though other forms of burner may of course be mounted instead ofthe one shown. The general arrangcment of the motor, burner andco-related parts is substantially as shown in my Patent No. 1,512,247dated October 21st. 1924.

The base 3 supports a driving motor 7 for the burner, said motor beingoperatively connected to the rotating parts of the burner by ahorizontal shaft 8 which extends from the motor to the burner throughthe opening 2.

By reason of this arrangement it will be seen that none of the vibrationor noise of the motor is transmitted direct to the furnace, especiallyif the "floor on which the base is mounted is of concrete, as is usuallythe case.

In connectionwith this arrangement, if

ton

provide a cover for the external parts of the burner structure, so asnot only to protect the motor and other accessories mounted on the basefrom harm, but to enable the air for the burner to be accuratelycontrolled.

This cover structure includes a rigid panel member 9 mounted on andprojectin upwardly from the base at the outer end thereof. This panelhas a lar e opening- 10 with a cooperating damper or door 11 which maybemanipulated to control the admission of air through the opening by anysuitable means. top of the panel to the sides and top of a frame 12Which projects outwardly from and surrounds the opening 2 is a casing13. Another similar strip 14 of the casing material but independent ofthe casing 13 extends from the bottom of the frame 12 to the adjacentend of the base 3, said strip being the full width of theframe and base.The casing members are both of flexible air-tight and fireproof fabricof suitable character. The casing 13 is securely but detachablyconnected to the sides and top of the frame and and, and also-along'thesides of the base y suitable means such as pins 15 on the rigid membersengaging eyelets 16 in the casing. These members may be of a nature suchas is commonly usedin connection with the side curtains of motorvehicles and the like.

The casing member 14 may be secured to the base and frame in the samemanner or permanently if desired.

Between the base and the furnace the sides of the casing 13 havelongitudinal flaps 17 along the bottom to fold under the side edges ofthe member 14, being detachably connected thereby by spin and eyearrangement therebetween such as that above described.

It is to be understood that not only are the casing members of air-tightmaterial, but the upper face of the base also is nonperforated so as tobe air-tight as well.

It will therefore be seen that an air-tight enclosure of vibrationlesscharacter surrounds the opening 2 and encloses the parts on the base,so'that' air for the burner can only pass through the panel opening 10.Since this panel is beyond the motor and other parts, the openin 10 isunobstructed throughout and the volume of air passing therethrough maytherefore be accurately.

controlled y manipulation of the door 11.

The main casing 13 being detachably mounted it may be easily folded backone Extending from the sides and way or the other or removed whendesired to get at the parts mounted on the base.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

lVhile this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations fromsuchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims. Having thus describedmy invention what I claim as new and useful and desire to secure byLetters Patent is:

1. An oil burner installation for a firebox having a side openingtherein comprising a base rigidly mounted outside the firebox, a rigidextension integral with the base projecting through the opening into thefirebox in spaced relation to the sides and bottom of the opening, anoil burner su ported by the extension at its inner end, an operatingmeans for the burner mounted on the base.

2. An oil burner installation for a firebox having a side openingtherein comprising a base rigidly mounted outside the firebox, a rigidextension from the base profurnace around said openin 3. In connectionwith a rebox having a side opening therein and an oil burner in thefirebox, a base fixed outside the firebox, operating means for theburner mounted on the base, a panel projecting upwardly from the outerend of the base, a horizontal member extending between the bottom of thefirebox opening and the adjacent end of the base, said member being thesame width as the opening and base, and a flexible casing passing aboutand attached to the sides and top of the panel and extending thence tothe sides and top of the firebox opening, detachable connections betweenthe firebox and easing, side flaps on the casing to engage the sideedges of the horizontal member, and detachable connections between saiflaps and member.

In testimony whereof I atfix my signature.
